We know that sc has an electron configuration of 3d'4s2 and cr has an electron configuration of 3d 4s1. using hartree-fock theory what is the difference in energy between sc in the electron configuration of 3d 4s2 and 3d 4s'? what is the energy difference between cr in the electron configuration of 3d54s1 and 3d44s"? if we assume that the coulomb integrals are the same: / = jm3d = 14s4s-iadss and the exchange integrals are the same: k kjasdk4sskas what do these energy differences simplify to? what does this tell us about the difference between the 3d and 4s orbitals (ε3d-e4s) in relation to the exchange integral k? note that for this problem ignore all the other electrons except the ones in the 4s and 3d orbitals.
